FURNACE.

SPECIFICATION forming part of Letters Patent No. 394,152, dated December11, 1888.

Application filed May 25, 1888- Serial No. 275,112, (No model.)

To aZZ whom it may concern.-

Be it known that I, .ToHN WINTERMUTE CASSIDY, a citizen of the UnitedStates, residing at Petaluma, in the county of Sonoma and State ofttllfol'lllti, have invented a new and useful Improvennmt in Furnaces,of which the following is a specification.

My invention relatcsto an inun'ovement in furnaces; and it consists inthe peculiar construction and combination of devices, that will be morefully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a front elevation of a furnace embodying myimprovements. Fig. 2 is a perspective view of the same, a portion of oneof the walls being broken awa to disclose the interior arrangement.

A represents the furnace or setting, which is built of brick or masonry,and is rectangular in shape, as shown. At a suitable distance from thelower side of the furnace, and extending longitudinally throughout theentire length of the same, is an arch, B, which forms the crown or roofof the fire-box G. Under the said tire-box is arranged. the pit I), andat the front end of the tire-box is the door E.

F represents the steam-boiler, which is arranged innnediately above thearch, and has one end projecting through the front wall of the furnace.From the rear end of the arch extends a pair of pipes, G, which arearranged horizontally to pass through the front wall of the furnace, andCOlllllllllllCitilQ with the lower end of an escape flue or pipe, II.Said pipes (l are arranged on opposite sides of the furnace, and thesaid pipe 11 has a curved hood or chan'lber, I, at its lower end, whichis arranged astride of the projecting front end of the boiler, and withwhich the pipes G comnumicate.

K represents the perforated pipe which extends through the tire-box. Tothe outer end of the said pipe is attached a pipe, Ii, which isconnected to a suitable oil-reservoir, (not shown,) and from theopposite side of said, pipe K and in line with the pipe L extends asteam-pipe, \I, which communicates with the boiler, and has asafety-valve, N, and a stop-cock, O. The pipe L is also provided withthe stop-cock P.

The operation of myinvention is as follows: Oil is fed to the pipe Kfrom the reservoir, and steam is admitted to said pipe from the boilerthrough the pipe M, so as to discharge the oil into the fire-box in theform of spray, thus reinlering the oil. actively combustible. The heatradiated from the arch is sufficient to generate steam in the boiler andheat the upper portion of the furnace, so as to adapt the same for d rving fruit and other purposes. The products of combustion escape fromunder the arch through the pipes G and H.

Having thus described my invention, I claim- 1. The furnace having thecrowned arch I at a suitable distance from its lower side, the boilerarranged above the furnace, incased within the walls thereof, and havingits front end extending through the front wall of the furnace, theescape-pipes G, arranged on opposite sides of the boiler above thecrown-arch and connnunicating with the fire-box at their inner ends, thevertical pipe II on the front side of the furnace, and the curved hoodor chamber I at the lower end of said pipe and astride the front end ofthe boiler and communicating with the pipe G, substantially asdescribed.

2. The furnace having the tire-box provided with the crowned arch B, andthe escape-pipes G, ext-endin forward from the rear end of said arch,and the pipe H, with which said pipes G communicate, substantially asdescribed.

3. The furnacehaving the crowned arch B at a suitable distance from itslower side, the boiler arranged above the furnace and iiicased withinthe walls thereof, the escapepipes G, arranged on opposite sides of theboiler above the crown-arch and com1nunieating with the tire-box attheir inner ends, and the pipe II, connnunicatin g with the outer endsof the pipes G, substantially as described.

In testimony that I claim the foregoing as my own I have hereto atfixedmy signature in.

presence of two witnesses.
